Lensless light-field imaging through diffuser encoding

Microlens array based light-field imaging generally suffers from an intrinsic trade-off between the spatial and angular resolutions. To this end, Scientists in China and German jointly proposed a lensless light-field imaging modality by using a diffuser as an encoder. Light rays can be decoupled from a detected image with adjustable spatio-angular resolutions, breaking through the resolution limitation of the sensor. This work indicates the possibility of using scattering media for lensless light-field recording and processing.
